Thanks, that makes me feel better, I was mainly worried about the sensors in the doors and around the wheel wells since that's where I hear a lot of rust starts. I guess as long as I'm careful and maybe avoid spraying directly on any connectors, it should be okay. Has anyone here had any experience with applying Crown or Rust Check on a newer car with lots of sensors?Look at this way: the areas where you'll apply these coatings will be the same parts of the car that are prone to water, dirt, grime and everything else that can cause rust. As long as you're applying them properly, as the manufacturer intended you have nothing to worry abotu.
Yeah, I'll ask the shop how they protect the sensors before getting it done, I didn't think to check that beforehandMost places know how to spray carefully around sensors but it's smart to ask them how they handle electronics first.
